Maxim Dolgolyov 358b761eb2 fix(biochem): статичный subnav без мигания + редизайн
Проблема: динамическая вставка через JS вызывала мигание (nav
появлялся через ~100ms после первого пейнта).

Решение: nav — статичный HTML в каждой странице, CSS — в <head>.
Активная вкладка проставлена в HTML (class bsn-active) — нет JS,
нет мигания, работает с первого байта.

Редизайн .biochem-subnav:
- frosted glass (backdrop-filter blur 14px, rgba 0.92)
- активная вкладка: фиолетовый фон-пилюля + нижняя линия 2.5px
- hover: мягкий фиолетовый фон
- mobile <560px: только иконки (bsn-label display:none)
- overflow-x auto + scrollbar-width:none — горизонтальная прокрутка без полосы
- biochem-nav.js сведён к no-op комментарию
